Optical Sapphire Applications

In the rapidly changing and challenging world of optical design, Swiss Jewel has been able to prove itself as a leader in supplying precision optical components that meet and exceed customer demands. Since 1920 we have been working with Synthetic Sapphire and understand how to accurately machine and polish this hard material. Below is brief overview of Sapphire Windows and Ball Lenses. We also routinely work with other optical materials, including Fused Silica, Glass, Calcium Fluoride, etc.

Sapphire Windows

Sapphire Windows used for short and long wavelength applications (UV and IR) exceed other optical materials in harsh environments, providing a barrier between elements. This is due to sapphire material’s high mechanical strength, temperature stability, wear resistance and chemical inertness.

Other window materials we supply are Quartz, Calcium Fluoride, BK-7


Typical applications:

  • Industrial and Medical OEM’s
  • Air and Gas Analyzers/Monitors
  • High Intensity Xenon Lamps
  • Cryogenic View Ports
  • UV and IR Windows and Lenses
  • Detector and Pressure Cells
  • Photodiodes
  • Bar Code Readers


Optical Balls Lenses & Hemispheres

We have over 45 stock sizes of Sapphire, Ruby, Quartz, Glass, and Cubic Zirconia balls & hemispheres. Off the shelf sizes from Dia. 005” to .375”, and larger sizes available.

We offer Grade 25 off the shelf and routinely supply Grades 5 and 10. Please refer to the AFBMA grade chart for more information on ball tolerances.


Typical Applications:

  • Fiber Optics
  • LEDs
  • Flow Meters
  • Bar Code Readers
